Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a technology which reduces a load applied to a power control unit even when the power control unit contacts with a component at an engine side.SOLUTION: A power control unit 20 is disposed at a lateral side of an engine disposed at a vehicle front side and supplies electric power to a motor for traveling a vehicle. The power control unit 20 includes: a housing 22; a vertical rib 24 protruding from a facing surface 22a of the housing 22, which faces the engine, to the engine side and extending in a vertical direction; and a guide protruding part protruding from the facing surface to the engine side and extending from the vertical rib 28 to the vehicle rear side. A height of the guide protruding part 28 from the facing surface gradually increases toward the vertical rib 28 in a vehicle fore and aft direction.SELECTED DRAWING: Figure 4 【課題】電力制御ユニットがエンジン側の部品と接触しても電力制御ユニットにかかる負荷を抑制する技術を提供する。【解決手段】車両前側に配置されるエンジンの側方に配置され、車両走行用のモータに電力を供給するＰＣＵ２０であって、筐体２２と、筐体２２のエンジンと対向する対向面２２ａからエンジン側に突出しており、上下方向に延びている縦リブ２４と、対向面からエンジン側に突出しており、縦リブ２８から車両後方に延びている案内凸部と、を備える。案内凸部２８の対向面からの高さは、車両前後方向において縦リブ２８に向かって徐々に高くなっている。【選択図】図４
